HMPROVEMENT INCEONIBINED PLOW AND GULTIVATOR.

Specification forming partof Letters Patent No. 9303, dated August 3, 1569. y

To @ZZ whom it may concern:

Be it known that I, SAMUEL HUBER, of Danville, in the county of Monteur and State of Pennsylvania, have invented a new and Improved Combined Plow and Cultivator; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this speciiication, in whicli- Figure l is a top View of my improved machine arranged as a cultivator or coverer. Fig. 2 is a detail sectional view of the same, taken through the line a' x, Fig. 1 looking in the direction of the arrows l. Filg. *3 is a detail sectional view of the saine arranged as a potatddigger, taken through the linea x, Fig. l, looking in the direction of "the arrows 2.

Similar letters of reference indicate l correspending parts.

My invention has for its object to furnish an improved plow, which shall be so constructed and arranged that it may be easily adjusted for use as afurrowing-plow, eoverer, eultivator, or potato-digger, andothich shall at the same time be simple in construction, easily adjusted, and effective in operation in whatever way it maybe used 5 and it consists in the construction and combination of the various parts of the machine, as hereinafter more fully described.

A is the tongue, to which the draft is applied, and the rear end of which is secured to the plate B by bolts C. j y

D are set-screws passing down through the plate B and connected with the rear endofthe tongue A, so that by loosening` ortightening the nuts upon the bolts C and turning the setserews D in or out the pitch of the pldw may be adjusted, as desired. f L l.,

E are the furrowing or cultivating plows, which are made in about the manner shown in Figs. l and 2-that is to say, 'somewhat similar to sections of a hollow cylinder. with inclined ends. The plows E are ,secured to the lower ends of the standards F-by bolts G.

The upper ends of the standards F are secured to the plate B by bolts H, as shown .in Figs. l, 2, and 3. Several sets of holes are formed through the plate B for the reeeptionof the bolts H, so that by shiftingthepositionl of said bolts H the plows may be adjusted nearer together or farther apart, or set at a different.

inclination, according to the particular use to which the machine is to be applied.'

Vhen the machine is to be used for digging potatoes, the standards F are shifted so as to bring their lower ends together, which said lower ends are then placed between and are bolted to the mold-boards of the double moldboard plow I by means of the same bolts by which the plows E were bolted to said standards F, as shown in Fig. 3.

To the rear parts of the mold-boards of the plow I are bolted or otherwise secured lingers J, bent into a suitable shape, so as to allow the soil raised by the plow I to pass through them, while the potatoes drop down upon the top of the ground.

K are the handles, the lower ends of which are bolted to the plate B and the upper end of which may be connected by a cross-bar or round, L, in the ordinary manner, as shown in Fig. 1. The handles K may be set at an inclination, if desired, for the convenience of the operator. A

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. The plate B, provided with several sets i of holes for the adjustable attachment of the plow-standards, substantially as herein shown and described, and for the purpose set forth.

2. The combination of the adjustable plowstandards F with the plate B, substantiallyas herein shown and described, and for the purpose set forth.

3. The plows E, constructed as described, in combination with the adjustable standards F and plate B, substantially as and for the purpose set forth.

4. The combination of the double moldboard plow I with the adjustable standards F and plate B, substantially as herein shown and described, and 'for the purpose set forth.

5. The combination ofthe iingersJ Withthe inold-boards of the double mold-board plow I, adjustable standards F, and plate B, substantially as herein shown and described, and for the purpose set forth.

SAMUEL HUBER.
